First, generate your signing certificates in the Xcode preferences. Click on the Accounts tab, select your user account and click Manage Certificates. Click the plus button and add the relevant certificates for the type of app you are developing.

Next, create a .p12 file that combines all of your certificates and private keys using these instructions.

Copy the .p12 format in base64:

base64 -i CertificateFile.p12 | pbcopy

Paste the output of the above command into a secret called CERTIFICATES_P12 and the password into CERTIFICATES_P12_PASSWORD into the GitHub Actions Secrets in the GitHub settings.

uses: apple-actions/import-codesign-certs@v3
with: 
  p12-file-base64: ${{ secrets.CERTIFICATES_P12 }}
  p12-password: ${{ secrets.CERTIFICATES_P12_PASSWORD }}

If you need to add multiple certificates, select them all in the keychain when creating your p12 file. You do not need multiple separate steps.

See action.yml for more details.
